Ingredients

1 lb box of Ziti Pasta

1.5 cups Mayonnaise

1/4 cup Sour Cream (or Mexican Crema)

1 Red Bell Pepper, finely diced

1 medium Red Onion, finely diced

2 stems Celery, finely diced

1 large Carrot, grated and minced

2 tsp Celery Salt (or to taste)

2 tsp Celery Seed (or to taste)

2 tbsp diced Pimientos with some liquid

1 lb block Cheddar Cheese, diced very small

1 bunch fresh Parsley, minced (optional)

2 tsp White Sugar

Instructions

Cook the Pasta:
Boil ziti pasta according to package directions until al dente. Rinse with cold water and drain thoroughly.

Prep the Veggies:
Finely dice the red onion, bell pepper, and celery. Add to a large mixing bowl. Sprinkle with celery salt and celery seed, then toss to coat. Add the diced pimientos with a bit of their liquid.

Add Carrot & Parsley:
Grate the carrot, then finely chop the grated pieces. Add to the veggie mixture. Mince fresh parsley if using and add it in.

Mix the Dressing:
In a separate bowl, whisk together mayonnaise, sour cream (or Mexican crema), and sugar. Add a pinch of celery seed and celery salt, if desired.

Combine Veggies & Dressing:
Pour the dressing over the veggie mix and toss well to coat. Let it sit for 15 minutes to allow flavors to blend.

Finish the Salad:
Add the cooked pasta to the dressed veggies and toss until evenly coated. Gently fold in the diced cheddar cheese.

Chill & Serve:
You can serve immediately, but for best flavor, cover and refrigerate for 4–6 hours or overnight.

Notes

The flavor gets better as it chills — it’s even more delicious the next day!

Use sharp or extra sharp cheddar for a bold cheese flavor.

Don’t skip rinsing the pasta — it stops the cooking and helps the salad stay fresh.

Great make-ahead dish for BBQs, cookouts, or meal prep.
